METHOD OF FABRICATION OF A PROPELLER BLADE IN COMPOSITE MATERIAL |
摘要 |
A propeller blade, which can belong to a fan without covering by an external casing, includes two portions fitted into one another and of different materials, generally composite, to resist various stresses, heating coming from a rotor or impacts of solid bodies. An internal portion includes a blade core, a blade shank and possibly a foam lining, and a preform of an outside portion is assembled to it by surrounding it closely before being completely formed by receiving its resin, which is placed into polymerization. A method for producing the propeller blade guarantees good assembly of the portions without defects of form, damage or deformation of a fiber weave. |
